Polson Brothers Logging Company began business in 1895 in Hoquiam. In 1903, the name was changed to Polson Logging Company. Polson was bought out by Rayonier in 1948.

The city of Hoquiam began as a manufacturing and export center for forest products, including pulp and paper, on the Hoquiam River on north side of Grays Harbor a dozen miles from the Pacific Ocean adjacent to Aberdeen in Grays Harbor County. With Aberdeen it continues to serve as the business and commercial center of southwestern Washington.
